Description

Conference control method and device, storage medium and electronic device

Technical Field

The embodiment of the invention relates to the technical field of computers, in particular to a conference control method and device, a storage medium and an electronic device.

Background

The video conference system comprises various participation devices such as MCU (Multipoint Control Unit multipoint control unit, namely video conference server), soft and hard terminals, recording and broadcasting server and the like. The terminal collects image and sound and sends the image and sound to the MCU through coding. The MCU fuses or does not fuse the images sent by the terminals according to meeting requirements, and sends the images to each participating terminal after sound mixing or unmixed sound mixing, so that the audio and video call of the multiparty meeting participants is realized. In a video conference, to ensure the interaction effect, we often need to perform linkage control such as "roll call speech" so as to realize the on-demand in-session requirement. In some video conference application scenarios of emergency command, the video conference system is used to meet the meeting communication requirement and the video monitoring requirement. Then a video conference still carries the video monitoring function, and new requirements are put forward on the "roll call talk" function. Users want to be able to implement the roll-call talk function of the traditional conference mode in the same video conference while also implementing a point-to-point conversation. The big meeting is used for video monitoring, and the small meeting through roll call simulation is used for point-to-point interactive dialogue, and only one video meeting exists actually, so that the video meeting is called as a meeting in a meeting and a meeting in a big meeting. The traditional roll call speaking operation does not involve the operation of a loudspeaker, so that the complex linkage operation cannot be realized, the same effect can be realized only through the roll call speaking, the loudspeaker is closed and the like which are controlled for multiple times, the operation is complex, the effect is chaotic, and the error is easy to occur. Therefore, the operation of implementing the point-to-point dialogue in the same video conference in the related art is complex, that is, the conference system in the related art has the problem of poor linkage control.

Aiming at the technical problem of poor linkage control of a conference system in the related technology, no effective solution is proposed at present.

In this embodiment, a conference control method is provided, fig. 2 is a flowchart of the conference control method according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:

step S202, receiving a control instruction for instructing a user using a first terminal to participate in roll call, wherein the first terminal is a terminal accessed into a conference system, and other terminals except the first terminal are also accessed into the conference system;

step S204, under the triggering of the control instruction, executing the following operations: opening a loudspeaker of the first terminal under the condition that the loudspeaker is not opened by the first terminal; and determining a second terminal included in the other terminals, and closing a speaker of the second terminal, wherein the second terminal is a terminal which is not allowed to turn on the speaker in an initial state and is turned on the speaker currently.

Through the steps, when a control instruction for instructing a user using a first terminal to participate in roll call speaking is received, the loudspeaker of the first terminal is started under the condition that the loudspeaker is not started by the first terminal, a second terminal is determined from other terminals connected to a conference system, and the loudspeaker of the second terminal is closed, wherein the second terminal is a terminal which is not allowed to start the loudspeaker and is started currently in an initial state. When a user corresponding to the first terminal is speaking, the purposes of controlling the starting of the loudspeaker of the first terminal in a linkage mode and the starting of the loudspeaker of the second terminal which is not allowed to be started in the initial state and is started at present can be achieved, and the purposes of achieving point-to-point conversation in the same video conference are also achieved. The problem that in the related art, when point-to-point conversation is to be realized in a video conference, the operation is complicated because of the control operation of multiple times such as speaking through roll calling, closing a loudspeaker and the like is avoided. Therefore, the technical problem of poor linkage control of the conference system in the related technology is solved, and the effect of improving the efficiency of linkage control of the conference system is achieved.

The main execution body of the above steps may be a server, such as a signaling service (or signaling server) in a conference system, or a processor, or a controller, or a processor configured on a storage device and having man-machine interaction capability, or a processing device or a processing unit having similar processing capability, but is not limited thereto.

In the technical solution provided in step S202, the conference system includes a plurality of participant terminals, such as the first terminal and the other terminals, where the other terminals may include one or more terminals, the participant terminals may be a mobile phone, a PC, a tablet, etc., when the conference system receives a control instruction for speaking a roll call, or the signaling server receives a control instruction for speaking a roll call, for example, receives a control instruction for instructing a user using the first terminal to speak a roll call, in practical application, the control instruction for speaking a roll call may be issued by a chairman terminal, or issued by a WEB browser terminal corresponding to the conference system, and the terminal used by the conference moderator may also include a chairman terminal, typically be set as a chairman terminal, and may set the chairman terminal through the WEB browser terminal before the conference starts, and in the conference process, the chairman terminal or the WEB browser terminal may issue the control instruction for speaking a roll call as needed. A control instruction for instructing to make a roll call may be received through this step S202.

In the technical solution provided in step S204, under the triggering of the control instruction of the roll call speech, the conference system may cooperatively control the related terminals to perform related operations, or the signaling server cooperatively controls some of the participant terminals to perform related operations, for example, perform some or all operations of opening a microphone (or simply opening a microphone), closing a microphone (or simply closing a microphone), opening a speaker, closing a speaker (or simply muting), etc., when the control instruction of the roll call speech indicates that the user using the first terminal is speaking, if the first terminal is not speaking, then, the operation of opening the speaker of the first terminal is performed by the coordinated control, and, for other terminals, when there is a second terminal whose initial state is not allowed to open the speaker and whose speaker is currently opened, then, the operation of closing the speaker of the second terminal is performed by the coordinated control, for example, a terminal (e.g., a third terminal) before the user of the current roll call first terminal is speaking, assuming that the initial state of the third terminal is not allowed to open the speaker, and the user of the third terminal is not allowed to open the speaker when the user of the roll call speech is instructed by the first terminal, and the user of the third terminal is determined to be opened at the initial state of the first terminal; if the speaker is allowed to be turned on in the initial state of the third terminal and is also turned on when the third terminal is previously roll-called, then no operation needs to be performed on the speaker of the third terminal, i.e. the third terminal at this time is not the second terminal. The initial state refers to that when a conference starts or before a roll call speaking operation occurs (i.e. a control instruction of roll call speaking is received), the chairman terminal or the WEB browser terminal can set an initial state in advance for all the terminals involved, wherein the initial state includes whether a microphone of the terminal is opened or not and whether a loudspeaker is opened or not, for example, the initial state of the terminal 1 (or the terminal ID 1) is in a microphone-off state and a loudspeaker-on state, that is, the terminal 1 cannot speak and can only hear, or the user of the terminal 1 cannot be received by other terminals even when speaking; for example, the initial state of the terminal 2 (or the terminal ID 2) is a microphone-on, speaker-on state, i.e., the user of the terminal 2 can speak or can hear the other user. In practical applications, the speaker states of all the participant terminals (i.e. whether the speakers are turned on or off) may be recorded through the first terminal list, and the microphone states of all the participant terminals (i.e. whether the microphones are turned on or off) may be recorded through the second terminal list, and during the conference, the chairman terminal or the WEB browser terminal may initiate an operation instruction to turn on or off the microphones or speakers of the terminals, and the first terminal list and the second terminal list may modify the speaker states and the microphone states of the respective terminals in real time, for example, when a roll call operation occurs (i.e. a control instruction of the roll call is received), the speaker states and the microphone states of the relevant terminals need to be modified; alternatively, the initial states of the speakers of all the participant terminals may be recorded by the first initial list, and the initial states of the microphones of all the participant terminals may be recorded by the second initial list.

In the above embodiments, the operation of turning on or off the speaker and microphone refers to the function of the server to turn on or off the speaker and microphone of the terminal, and is not related to the actual speaker and microphone of the terminal, for example, taking the case that the microphone of a certain terminal is in the off state as an example, it refers to that the server does not collect or receive the sound signal of the terminal, even if the user of the terminal turns on the microphone function on the terminal, the server does not receive the sound signal of the terminal, and it is equivalent to the turn-off operation performed on the microphone of the terminal.

Through the embodiment, when the user corresponding to the first terminal is speaking, the purposes of controlling the loudspeaker of the first terminal to be started in a linkage mode and closing the loudspeaker of the second terminal which is not allowed to be started in the initial state and is started at present can be achieved, and the purpose of achieving point-to-point conversation in the same video conference is achieved. The problem that in the related art, when point-to-point conversation is to be realized in a video conference, the operation is complicated because of the control operation of multiple times such as speaking through roll calling, closing a loudspeaker and the like is avoided. Therefore, the technical problem of poor linkage control of the conference system in the related technology is solved, and the effect of improving the efficiency of linkage control of the conference system is achieved.

In an alternative embodiment, the method further comprises: under the triggering of the control instruction, the following operations are also executed: and turning on the microphone of the first terminal and turning off the microphones of the other terminals.

In the above embodiment, the operation of turning on the microphone and the operation of turning off the microphones of the other terminals may also be performed on the first terminal, so that only the user of the chairman terminal (or called conference host) and the user using the first terminal may use the microphones, that is, both may speak, while the user of the other terminal does not allow speaking, thereby achieving the purpose of performing a point-to-point conversation in the video conference. In practical applications, the speakers of other terminals may be muted as a whole or the initial state of the speakers may be set to allow the speakers to be turned on for some of the other terminals, for example, there may be a plurality of commentators in some conferences, when a user (such as a player or a participant) of a terminal of a presenter's name speaks, only the presenter, the callee may use the microphone, and the user of the other terminal may not use the microphone, but some of the terminals (such as the terminals used by the commentators) may be set to turn on the speakers so that a conversation between the presenter and the callee may be heard, and optionally, the initial state of the terminal used by the other player may be set to disallow the speakers to be turned on. Through the embodiment, the aim of executing more linkage control on the terminal accessed to the conference system is fulfilled, and the effect of further improving the linkage control efficiency of the conference system is realized.

In an optional embodiment, the determining the second terminal included in the other terminal includes: acquiring a first initial list and a first terminal list, wherein the first initial list is used for recording the identifiers of the terminals of a group of terminals in the conference system, which are closed to the loudspeaker, before a control instruction of roll call speaking is received for the first time in a current conference, the group of terminals comprises the first terminal and the other terminals, and the first terminal list is used for recording the identifiers of the terminals of the group of terminals, which are closed to the loudspeaker at present; and determining the second terminal from the other terminals according to the first initial list, the first terminal list and the identification of a third terminal, wherein the third terminal is used for indicating a terminal used by a user speaking before the user using the first terminal to participate in roll call speaking, and the other terminals comprise the third terminal.

In the above embodiment, the first initial list may be used to record the identity of a terminal in the conference system that has turned off a speaker before a control instruction for roll-call speech is first received in the current conference, that is, the first initial list is used to record the identity of a terminal in the group of terminals whose initial speaker state is off (i.e., the speaker is turned off), and the initial state corresponding to a terminal not included in the first initial list is a permission to turn on the speaker; the group of terminals comprises the first terminal and other terminals, and the number of the terminals currently participating in the conference is 10, and the terminal IDs are respectively: ID 1-ID 10, for example, the first initial list includes ID6, ID9 and ID10, that is, the terminals corresponding to ID6, ID9 and ID10 are not allowed to turn on the speakers, and the other terminals (ID 1-ID 5 and ID 7-ID 8) are allowed to turn on the speakers, and the initial states of all the terminals can be set by the chairman terminal or the WEB browser terminal; the first terminal list is used for recording the identification of the terminal of which the speaker is currently turned off in a group of terminals, for example, when a roll call event occurs (or a control instruction of roll call is received) during a conference, the speaker state of the relevant terminal needs to be adjusted, after the speaker state of the terminal is adjusted, the speaker state of the terminal is presented in the first terminal list in real time, for example, when the terminal ID5 is adjusted from an allowed on state to an off state, the ID5 is recorded in the first terminal list, and the first initial list is only used for recording the initial state of the speaker of the terminal, and no adjustment is needed. And determining whether the other terminals are called third terminals, wherein the third terminals are terminals used by the user speaking before the user of the first terminal is called to speak, or can be called as terminals used by the user speaking last (or simply called last called terminals), if the user of the first terminal is the first called user in the current meeting, the other terminals do not comprise the third terminals, and when the third terminal which is called last exists in the other terminals, the second terminals can be determined from the other terminals according to the first initial list, the first terminal list and the identification of the third terminal. For example, ID6 is included in the first initial list, and ID6 is the identity of the last roll-up terminal (corresponding to the third terminal described above), and when ID6 is roll-up, its speaker is adjusted to be in a state allowing to be turned on, that is, ID6 is deleted in the first terminal list, that is, the speaker of ID6 is currently turned on, and at this time, ID6 may be determined as the second terminal. By the embodiment, the purpose of determining the second terminal from other terminals is achieved.

In an optional embodiment, the determining the second terminal from the other terminals according to the first initial list, the first terminal list, and the identifier of the third terminal includes: and determining the third terminal as the second terminal under the condition that the first initial list comprises the identification of the third terminal and the first terminal list does not comprise the identification of the third terminal.

In the above embodiment, for example, the initial state of the speaker including ID6 in the first initial list, that is, ID6, is not allowed to be turned on, and assuming that ID6 is the identity of the last roll-call terminal (corresponding to the third terminal described above), the speaker thereof will be adjusted to the state of allowing to be turned on when ID6 is roll-called, that is, the speaker of ID6 will be deleted in the first terminal list, that is, the speaker of ID6 is currently turned on, and at this time ID6 may be determined as the second terminal. By the embodiment, the purpose of determining the second terminal from other terminals according to the first initial list and the first terminal list is achieved.

In an alternative embodiment, the method further comprises, upon triggering by the control instruction, after performing the following operations: updating the first terminal list based on the latest state of the group of terminals to obtain an updated first terminal list, and updating the second terminal list based on the latest state of the group of terminals to obtain an updated second terminal list, wherein the second terminal list is used for recording the identification of the terminal of which the microphone is turned off currently in the group of terminals.

In the above embodiment, the first terminal list may be updated based on the latest state of a group of terminals, and the second terminal list may be updated, for example, if the initial state of the first terminal before the roll call is made is that the speaker is not allowed to be turned on (i.e., the first initial list contains the identifier of the first terminal, such as ID 1), and the microphone is not allowed to be turned on, in fact, the first terminal list also contains the identifier ID1 of the first terminal, and when the user of the first terminal is currently roll call, the speaker of the first terminal and the microphone of the first terminal will be turned on, at this time, the identifier ID1 of the first terminal will be deleted in real time in the first terminal list, i.e., the first terminal list is updated in time, and similarly, the second terminal list will be updated according to the latest state of each terminal in the group of terminals. By the embodiment, the purpose of timely updating the first terminal list and the second terminal list is achieved, so that the current states of the microphone and the loudspeaker of each terminal, namely whether the current states are on or off, can be mastered in real time.

In an alternative embodiment, the method further comprises: synchronizing the updated first list of terminals and the updated second list of terminals to a media service to instruct the media service to provide a first sound signaling service to terminals in a first set of terminals including terminals of the set of terminals other than the terminals included in the updated first list of terminals and to provide a second sound signaling service to terminals in a second set of terminals including terminals of the set of terminals other than the terminals included in the updated second list of terminals.

In the above embodiment, the updated first terminal list and the updated second terminal list may be synchronized to the media service, so that the media service may provide the relevant terminal with the sound signal transmission service and the sound signal reception service according to the updated first terminal list and the updated second terminal list. For example, for the terminals included in the updated first terminal list, audio signals of other terminals are not transmitted thereto, that is, the terminals in the first terminal list cannot hear the sound of other terminals, and for the terminals not included in the updated first terminal list (that is, the terminals in the first terminal set) a sound signal transmission service is provided; similarly, the terminals included in the updated second terminal list are not subjected to the voice signal receiving service, and the terminals not included in the updated second terminal list (i.e., the terminals in the second terminal set) are subjected to the voice signal receiving service. The media service can be controlled or regulated according to the updated first terminal list and the updated second terminal list, so that the aim of carrying out linkage control on the participant terminal is fulfilled.

In an alternative embodiment, the method further comprises, upon triggering by the control instruction, after performing the following operations: and under the condition that an end roll call floor control instruction is received, carrying out recovery operation on each terminal in a group of terminals according to a first initial list and a second initial list, wherein the group of terminals comprises the first terminal and the other terminals, the first initial list is used for recording the identification of the terminal with a loudspeaker closed in the group of terminals before the roll call floor control instruction is received for the first time in a current conference, and the second initial list is used for recording the identification of the terminal with a microphone closed in the group of terminals before the roll call floor control instruction is received for the first time in the current conference.

S406, when there is no last roll-call person, that is, the roll-call speech operation object (roll-call person) in the step S402 is the first roll-call person, at this time, the current "off microphone" list and the "off speaker" terminal list are backed up, and then step S410 is entered; for example, the clos micdevices and mute devices list in (7) above is copied into clos micdevice protected and mute device protected;

the closeMICDevices terminal list in (7) above may be used to record terminal information (such as an identifier of a terminal) that has been currently closed, the muteddevices terminal list in (7) above may be used to record terminal information (such as an identifier of a terminal) that has been currently muted, assuming that there are 10 terminals currently participating in the conference, and the terminal IDs are respectively: ID1 to ID10, for example, ID1 to ID5, ID7 to ID8, etc. are included in the closed MICDevices terminal list, while ID1 to ID9 are included in the muteDevices terminal list or are empty, and the terminal identifications included in the closed MICDevices terminal list and the muteDevices terminal list may be the same or different.

S408, when the determination result in the above step S404 is yes, the previous celebrity (or the identity of the roll-call terminal, for example, ID 5) before the celebrity, that is, the object of the roll-call speech operation (roll-call person) in step S402 is recorded.

S410, starting traversing all the participant terminals, and executing microphone closing and loudspeaker closing operations on the related terminals;

for example, when the terminal X is not the current roll-up person and is also not the chairman terminal, and the close mic devices list is not recorded, the "close microphone" operation is performed on the terminal X; if the terminal X is the last roll-up person recorded (corresponding to step S408, e.g., ID 5), and is recorded in the muteDevices save list, and is not recorded in the muteDevices, then performing a "turn-off speaker" operation on the terminal X;

s412, updating the latest roll-up person, for example, the latest roll-up person (for example, the roll-up terminal is ID 6), namely, when other terminals are roll-up after the ID6, the roll-up person recorded in the step S408 is ID6;

s414, executing microphone starting and loudspeaker starting operations on the latest roll-up person;

s416, performing video picture related control operation, for example, displaying images of a user (such as a host) corresponding to the chairman terminal and a roll-up person (i.e. a user of the roll-up terminal) in a shared screen, wherein the images can be viewed, and optionally, pictures of other meeting places or participant terminals can be displayed in the screen;

S418, synchronizing the latest closed speaker terminal list and the latest closed microphone terminal list to the media service, so that the media service can collect or transmit sound signals according to the latest closed speaker terminal list and the latest closed microphone terminal list, for example, for terminals included in the latest closed microphone terminal list, collect no sound signals thereof, and collect only sound signals for terminals not included in the latest closed microphone terminal list; similarly, the terminal included in the latest "off speaker" terminal list cannot hear the voice of the other terminal without transmitting the audio signal of the other terminal.
